Afghan call up for self employed

Swinger

I am off to Afghanistan next autumn, but as I am self employed was wondering what I need to take up to Chilwell. No official info as yet, but have any of you any experience? There is also some financial help for when I'm away to keep the business going, as by the time I've paid for someone to do my work I will probably make a substantial loss on the next years accounts, but any claim needs to be made when I return apparently, any advice gratefully received thanks.
